I too am new to this site and I am also looking for a part for an airco welder. It's a 200 hornet special, made by P & H. I can't find any real part numbers. The welder model is 2DDC LMB C. I need a rheostat that's 225 Watts, but I don't know the ohms (I checked it and the ohmmeter showed 8 ohms, don't know if that's right). The Inst. Book is 1350. Don't have a Serial #. I've tried everyone, and everything I can think of. Can anyone help me???
Thanks,
Seth
